I already have almost all protein shaker bottles…protein shaker bottles with filters, blenders and blenders. They cannot approach the quality, durability and functionality of this cup.
I have been using the Helixmix shaker for about a month. There is no leakage. There are no bulky internal parts. The simple, well-thought-out design gives me unlimited mixing effects every time.
In addition to working directly, it looks very clean.
Spend more money to buy a durable cup. It looks terrible. It is made in the United States and can get the job done.
